Label literacy
Built around how cosmetic packaging actually marks traceability.
LOT, BATCH, EXP and PAO markings answer different questions. Cosmetic LOT focuses on the encoded production batch, then applies brand-specific rules to recover the manufacturing date when the rule is known.
EXP
A visible expiry or best-before marking when the manufacturer prints one directly on the label.
PAO
The open-jar period-after-opening symbol, such as 12M or 24M. It is not the same as the manufacturing date.
Workflow
A focused process for inspection teams and careful consumers.
01
Find the code
Check the bottle base, tube crimp, box flap, label edge, or the area near the barcode.
02
Choose the brand
Brands often use different internal encoding patterns, so the brand selection matters.
03
Review the result
Use the decoded manufacturing date and estimated expiry as an inspection aid, not a replacement for the product's printed label.
